THS4225D

Instrumentation, Op Amps, Buffer Amps Overview

The THS4225D is a single-channel, low-distortion, high-speed voltage feedback operational amplifier with rail-to-rail output. It operates from a supply voltage range of 3 V to 15 V and consumes 14 mA per channel. Key electrical parameters include a gain-bandwidth product of 120 MHz, a slew rate of 975 V/µs, and an open-loop voltage gain of 100 dB. The device features ultra-low distortion with second and third harmonic distortion reaching -90 dBc and -100 dBc respectively at 5 MHz. It includes a power-down mode for energy savings and is housed in an SOIC-8 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SOIC-8 plastic small outline package when sourcing. Confirm that the component includes the power-down feature, distinguishing it from the non-power-down THS4221 variant within the same family. Ensure compatibility with the required operating temperature range and thermal dissipation requirements for the selected PCB layout.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring high-speed signal processing with minimal harmonic distortion. The rail-to-rail output allows for maximum dynamic range in low-voltage systems. Consider the power-down pin if system-level power management during idle states is necessary. Verify that the 100 mA output drive current meets the load requirements of the downstream circuitry.

Instrumentation, Op Amps, Buffer Amps Part Context

The THS4225D belongs to the THS422x family of high-speed operational amplifiers manufactured by Texas Instruments. This family includes single-channel devices like the THS4221 and THS4225, as well as dual-channel variants such as the THS4222 and THS4226. The THS4225 specifically adds a power-down control pin compared to the standard THS4221, offering flexibility for power-sensitive applications while maintaining identical high-speed electrical characteristics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

THS4221D serves as a direct functional substitute if the power-down feature is not required.
